DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] Please refer to Figures 1-4 The foldable mobile civil air defense water storage support provided by the embodiments of the present application comprises a folding chassis 100, a lifting caster 200, a water storage device 300, a fixing device 400 and a limiting device 500.

[0029] The folding chassis 100 is composed of a middle frame 110 and two left and right side frames 120. The left and right sides of the middle frame 110 are respectively hingedly connected to the two side frames 120 through pin shafts 111. The folding chassis 100 is provided with a limiting device 500 for limiting the unfolding angle of the folding chassis 100. The middle frame 110 and the two side frames 120 are both square steel structure frames. The bottom front and rear ends of the middle frame 110 and the side frames 120 are respectively provided with reversible leg supports 101. The leg supports 101 can support the square steel structure frames after being turned down. The middle frame 110 and the leg support 101 below it and the side frame 120 and the leg support 101 below it are both provided with fixing devices 400 for fixing the positions of the leg supports 101 when the leg supports 101 are supporting. The middle frame 110 and the side frames 120 are provided with support plates 102. The left and right sides of the middle frame 110 are respectively provided with two frame lugs 103. The side frames 120 are also respectively provided with two frame lugs 103 on the side hingedly connected to the middle frame 110. The frame lugs 103 of the middle frame 110 and the side frames 120 are connected through pin shafts 111. The front and rear ends of the middle frame 110 are respectively provided with caster mounting seats 210. The caster mounting seats 210 are installed with lifting casters 200. The water storage device 300 is arranged on the folding chassis 100. The water storage device 300 is a water storage bag.

[0030] In the embodiment of the present application, the folding base 100 is composed of a middle frame 110 and two side frames 120, and the middle frame 110 and the two side frames 120 are hingedly connected by a pin shaft 111, so that the water storage support can be easily folded and stored in the non-use state, occupying less space. In this way, the device can be conveniently stored and transported during emergency rescue and civil air defense facility storage and transportation, solving the problem of large space occupation of the existing rigid water storage device.

[0031] At the same time, the water storage bag is used as the water storage element 300 in the embodiment of the present application, which is placed on the folding base 100. Compared with the traditional rigid metal water tank, the use of the water storage bag can significantly reduce the overall weight of the device, and it can also be quickly drained and stored after use, thereby improving the convenience of transportation. Moreover, the lightness of the water storage bag combined with the folding structure of the folding base 100 makes the device easier to operate and move, thereby avoiding the inconvenience of moving the existing water storage device due to its large weight.

[0032] In addition, the bottom front and rear ends of the middle frame 110 and the side frame 120 are respectively provided with a leg support 101, which can be flipped down to support the frame, and the position of the leg support 101 can also be stabilized by the fixing member 400. Such a structure ensures the stable support of the water storage element 300 in the unfolded state. In addition, the application is provided with a wheel mounting seat 210 at the front and rear ends of the middle frame 110, and a lifting wheel 200 is installed. This way, the lifting wheel 200 is concentrated on the middle frame 110, making the water storage support more balanced during movement and use, and facilitating flexible adjustment of the position in different site conditions. At the same time, the configuration of the lifting wheel 200 improves the stability of the movement of the water storage support, which is helpful for quick adjustment in emergency situations, and improves the deficiencies of the existing mobile water storage equipment in movement.

[0033] Moreover, the application installs a limiting device 500 on the folding base 100 to limit the unfolding angle of the folding base 100. By controlling the relative angle between the side frame 120 and the middle frame 110, the folding base 100 can maintain at a suitable angle after unfolding, improving the stability of the water storage support during unfolding and avoiding the problem of unstable structure caused by excessive unfolding. Moreover, when the water storage support is stored or moved after storage, the folding base 100 can also maintain a relatively stable folding state, so that the water storage support can be safely used whether it is unfolded or moved after storage.

[0034] In some embodiments, the foldable mobile civil air defense water storage support further comprises guardrails 600 located at the front and rear ends of the folding chassis 100 to protect the water storage element 300, the bottom ends of the two guardrails 600 are fixedly connected with the front and rear ends of the middle frame 110, the front and rear ends of the two side frames 120 are respectively hingedly connected with the two guardrails 600 through gas springs 700, the upper ends of the guardrails 600 are respectively hingedly connected with a gas spring 700 on the left and right sides, and the other end of the gas spring 700 is hingedly connected with the side frame 120 on the same side.

[0035] The foldable mobile civil air defense water storage support of the present embodiment is provided with guardrails 600 at the front and rear ends of the folding chassis 100, and the guardrails 600 are fixedly connected with the middle frame 110 through the bottom ends. This structure provides additional boundary protection for the water storage element 300 during the unfolding and use of the water storage element 300, which can effectively prevent the water storage bag from being accidentally displaced or tipped over. The placement of the water storage element 300 is more stable due to the presence of the guardrails 600, which helps to maintain better safety during use of the device.

[0036] The upper end of the guardrail 600 is hingedly connected with the gas spring 700, and the other end of the gas spring 700 is connected to the side frame 120 through a hinge point. This arrangement makes the guardrail 600 more flexible during unfolding and folding. The presence of the gas spring 700 provides a moderate supporting force, making the adjustment of the guardrail 600 smoother. Because the gas spring 700 can provide stable supporting force and buffering effect, the user can reduce the difficulty of operation when folding or unfolding the guardrail 600, thereby improving the convenience and reliability of the device in actual operation.

[0037] In some embodiments, the upper ends of the guardrails 600 are respectively fixedly provided with a guardrail lug 610 on the left and right sides, and the upper ends of the side frames 120 are respectively fixedly provided with a gas spring lug 121 on the front and rear sides, and the upper and lower ends of the gas spring 700 are respectively hingedly connected with the guardrail lug 610 and the gas spring lug 121.

[0038] In specific applications, by providing the guardrail lug 610 on the left and right sides of the upper end of the guardrail 600 and the gas spring lug 121 on the upper end of the side frame 120, the hinge connection between the guardrail 600 and the gas spring 700 can be more stable. The combination of the guardrail lug 610 and the gas spring lug 121 also allows the gas spring 700 to maintain a better force angle during folding and unfolding, further improving the reliability of the connection structure.

[0039] Moreover, the guardrail support ears 610 and the gas spring ear seats 121 are arranged at reasonable positions, the guardrail support ears 610 are arranged at the left and right sides of the upper end of the guardrail 600, close to the key support position of the guardrail 600, and the gas spring ear seats 121 are arranged above the front and rear ends of the side frame 120, so that the two form stable fulcrums after assembly, and the water storage support forms a protection structure composed of the guardrail 600 and the gas spring 700 on the front and rear sides, thereby improving the overall stability of the device.

[0040] In addition, the combination of the guardrail support ears 610 and the gas spring ear seats 121 can make the connection of the guardrail 600 and the side frame 120 more flexible. The upper and lower ends of the gas spring 700 are hinged to the guardrail support ears 610 and the gas spring ear seats 121 respectively, which gives the side frame 120 a moderate range of motion. This flexibility is particularly important when the side frame 120 is unfolded and folded, and the user can complete the operation without exerting excessive force. At the same time, the assistance of the gas spring 700 in the opening and closing process of the side frame 120 can effectively prevent damage to the side frame 120 due to improper operation, further prolonging the service life of the water storage support.

[0041] In some embodiments, the fixing member 400 is a round steel with a bending structure at one end, the middle frame 110 and the left and right side frames 120 are each provided with four fixing members 400, the middle frame 110 and the side frames 120 are each provided with two fixing members 400 at the front and rear ends, the middle frame 110 and the side frames 120 are each provided with frame support ears 106 on the outer sides of the front and rear ends, the outer side of the leg support 101 is provided with leg support ears 104 corresponding to the positions of the frame support ears 106, and the fixing member 400 is vertically inserted into the frame support ears 106 and the leg support ears 104 to fix the position of the leg support 101.

[0042] The embodiment uses a round steel with a bending structure as the fixing member 400 to provide reliable guarantee for the stable support of the leg support 101. The middle frame 110 and the side frames 120 are respectively provided with frame support ears 106 on the outer sides of the front and rear ends, corresponding to the leg support ears 104 on the outer side of the leg support 101. The fixing member 400 is vertically inserted into the frame support ears 106 and the leg support ears 104 to firmly connect the leg support 101 and the frame. This fixing method not only is simple to operate, but also enhances the stability of the leg support 101 in the supporting state, avoiding the problem of structural instability caused by loosening of the leg support 101.

[0043] The fixing member 400 is flexible and versatile in structure, the bending structure of the fixing member 400 allows it to be easily inserted into the frame support ears 106 and the leg support ears 104, and fixed by a simple vertical insertion method, reducing the demand for installation space.

[0044] In some embodiments, the support plate 102 is a perforated plate, a plurality of through holes are uniformly arranged on the support plate 102, and the support plate 102 is fixed on the middle frame 110 and the side frame 120 by welding.

[0045] The support plate 102 is designed as a perforated plate, a plurality of through holes are uniformly arranged on the support plate 102, so that the support plate 102 can not only provide stable support, but also reduce the overall weight of the support plate 102 due to the presence of the through holes, thereby reducing the self-weight of the water storage support. In addition, the through holes also play a role in drainage, which can effectively remove excess moisture or accumulated water around the water storage device 300 during use, thereby preventing the support plate 102 from being overloaded due to excessive accumulated water.

[0046] The support plate 102 is fixed on the middle frame 110 and the side frame 120 by welding, which enhances the firmness of the overall structure. The welding connection method ensures that the support plate 102 will not loosen during long-term use, thereby maintaining the stability of the support performance.

[0047] In some embodiments, the bottom ends of the middle frame 110 and the side frame 120 are hingedly connected to the leg support 101 by hinges 105. This hinged connection method allows the leg support 101 to be easily flipped down and supported, and can be easily folded when not in use. Compared with the traditional fixed leg design, the hinge connection method significantly improves the folding and convenience of the water storage support. The leg support 101 can firmly support the frame and provide stable support when unfolded, and can be folded and stored when not in use, thereby occupying less storage space. The reasonable hinge design of the present embodiment allows the water storage support to be deployed and stored in a short time, thereby greatly improving the work efficiency and adaptability.

[0048] In some embodiments, the limiting device 500 includes a limiting sleeve 510, an insertion handle 520, and a locking bolt 530. The limiting device 500 can enhance the stability of the support when unfolded and when the side frame 120 is folded. The left and right sides of the front and rear ends of the middle frame 110 are fixedly provided with the limiting sleeve 510, and the front and rear ends of the side frame 120 are also fixedly provided with the limiting sleeve 510 near the middle frame 110. The outer end of the limiting sleeve 510 is provided with a insertion hole for the end of the insertion handle 520, the limiting sleeve 510 of the side frame 120 is detachably connected with the insertion handle 520, and the locking bolt 530 is arranged on the limiting sleeve 510 for locking the end of the insertion handle 520. The insertion handle 520 is a U-shaped rod structure.

[0049] In use, the limiting sleeves 510 of the middle frame 110 and the side frames 120 can be connected together through the insertion handle 520. The insertion handle 520 is inserted into the insertion hole of the limiting sleeve 510 to fix the middle frame 110 and the side frames 120 at a certain angle, thereby limiting the relative movement of the middle frame 110 and the side frames 120. Such a design enables the folding chassis 100 to maintain a stable angle after unfolding, avoids excessive unfolding or loosening of the frames, and improves the stability of the overall structure. At the same time, the disassembly of the limiting device 500 is extremely simple, so that the water storage support can be quickly stored when not in use. When folding the side frames 120 on the left and right sides of the middle frame 110, both side frames 120 are turned inward, so that the two side frames 120 are folded, and then the insertion handle 520 is inserted into the limiting sleeve 510 of the middle frame 110 and the side frames 120 to maintain the shape of the support after storage.

[0050] Moreover, the limiting sleeves 510 are provided, so that the limiting device 500 can be used more flexibly. By inserting the insertion handle 520 into the limiting sleeve 510 and fixing it with the locking bolt 530, the user can quickly fix the middle frame 110 and the side frames 120 at a predetermined unfolding angle. The U-shaped rod structure of the insertion handle 520 makes insertion and disassembly more convenient, and the operator can quickly complete the construction and disassembly of the water storage support without additional tools. In addition, the locking bolt 530 is provided to ensure the firmness of the connected insertion handle 520, avoid loosening or deformation of the frames due to external force, and enable the water storage support to be used safely.

[0051] In some embodiments, the water storage bag used by the water storage device 300 is made of flexible material, such as a PVC water storage bag. The periphery of the water storage bag is provided with a reinforcing belt for connecting with the folding chassis 100.

[0052] The water storage bag made of flexible material used by the water storage device 300 can effectively reduce the overall weight. The use of flexible material enables the water storage bag to be easily folded and stored in a non-use state, thereby saving storage and transportation space. The periphery of the water storage bag is provided with a reinforcing belt for connecting with the folding chassis 100. The reinforcing belt further enhances the stability of the water storage bag when placed on the folding chassis 100. Moreover, the installation mode of the reinforcing belt enables the water storage bag to be easily fixed on the folding chassis 100 without the need for complex connecting components.

[0053] The foldable mobile civil air defense water storage support provided by the embodiments of the present application can be used in the following ways in actual application:

[0054] (1) Transportation and storage

[0055] In the human defense and emergency rescue scene, the water storage support usually needs to be deployed in advance or quickly deployed in emergency. Since the folding chassis 100 and flexible water storage bag are adopted in the embodiment of the present application, the space occupied by the water storage support during storage and transportation is greatly reduced, and the water storage support can be conveniently stored in the emergency reserve warehouse and be ready at any time. During transportation, the support can be compactly stored after folding, avoiding occupying too much space, and being suitable for the limited storage space in the human defense facility. Especially in post-disaster rescue or wartime, it can be quickly transported to places where water sources are needed.

[0056] (2) Quick deployment and installation

[0057] When a disaster or emergency occurs and emergency drinking water needs to be provided, the operator can quickly take the water storage support from the storage area. First, unfold the folding chassis 100, keep the unfolded folding chassis 100 stable through the limiting device 500, then turn over the leg frame 101, and fix it in place with the fixing member 400 to form a stable support structure. At this time, the folding chassis 100 forms a usable water storage support frame to provide support for the water storage bag and ensure that the water storage bag does not tilt or shift during use.

[0058] (3) Installation and fixation of the water storage bag

[0059] When installing the water storage bag, the operator takes out and unfolds the flexible water storage bag and easily places it on the folding chassis 100. The four corners of the water storage bag are connected to the chassis 100 through the reinforcing belt to prevent the water storage bag from shifting due to external forces after being filled with water. This quick installation method is particularly suitable for emergency water supply devices that need to be deployed urgently in the human defense scene.

[0060] (4) Storage and storage after use

[0061] In the human defense scene, the storage and storage of the equipment are also important. When the water storage support of the embodiment of the present application is used up, the operator can quickly fold up the water storage support. First, empty the water in the water storage bag, then remove the reinforcing belt, and easily fold the water storage bag. Then, turn over the leg frame 101 and loosen the fixing member 400 to fold the leg frame 101 into a folded state to reduce the occupied space. Finally, fold the side frame 120 to facilitate storage in the emergency material storage area and prepare for the next use. The whole process is simple, convenient and fast, and is suitable for quick response emergency rescue scenes.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
